For decades, the name “Nelson” seemed nearly synonymous with exhaust systems. Since
its founding in 1939, the Wisconsin
company had established itself as a
significant supplier of engine exhaust
systems and components serving the
on-highway, off-highway and stationary
and industrial engine markets.

Indeed, its success was a big reason
why the name disappeared for a time,
as the company was purchased by
global engine giant Cummins in the late
1990s, making it part of the company’s
Components Group under Cummins
Emission Solutions.
